Abstract:
This research was carried out to evaluate the allelopathic effect of leaves aqueous extract of Azadirachta indica on germination and seedling growth of Vigna radiata. Different methods were used to preparing leaves aqueous extract. Germination percentage and seedling growth of V. radiata significantly decreased gradually as the concentration of the aqueous leaves extracts of A. indica increased in comparison with water control. Severe toxicity was observed at high concentrations and moderate toxicity at low concentrations in comparison with water control. Aqueous leaves extract significantly inhibited root length more than shoot. These results indicated that some kind of inhibitor(s) was the responsible agent for the phytotoxic effect of A. indica on germination and seedling growth of V. radiata.
